AUTOMOBILE RADIATOR GAY.

Application filed March 7, 1922. Serial No. 541,808.

To all whom it may concern:

Be it known that I. HARRY A. hLn'BERRY, a citizen of the United States.and a resident of McLeansboro, in the county of Hamilton and State ofIllinois, have invented a new and useful Automobile Radiator Cap, ofwhich the following is a specification.

My invention relates to automobile radiator caps and its principalobject is to provide a radiator cap which will permit the radiator to befilled with water without removing the cap from the radiator.

A further object of. the invention is to provide a radiator cap providedwith a, valve normally urged to closed position and adapted to be movedto open position upon pressing the nozzle of a hose thereagainst, thusthe necessity of removing the cap from the radiator is obviated.

Still another object of the invention is to provide a radiator cap whichwill be universal to all automobile radiators and which, at the sametime, will be inexpensive and practical in use.

With the preceding and other objects and advantages in mind, theinvention consists in the novel combination of elements, constructionand arrangement of parts and operations to be hereinafter more fullydescribed, claimed and illustrated in the accompanying drawing, inwhich;

Figure 1 is a plan view of the radiator igure 2 is a side elevation ofthe cap mounted on the nipple of a radiator;

Figure 3 is a vertical sectional view of the same; and

Figure 4 is a bottom planvie'w of the device.

Referring in detail to the drawingwherein similar characters ofreference designate similar parts throughout the several views, thenumeral 5 designates theusual threaded nipple of an automobile. radiatorwhile the numeral 6 designates the cap threaded thereon. The cap 6 isprovided with a central openin 7 in which a valve 8 is normally engageIn order to limit the upward moveme'ntof the valve the cap 6 isprovidthe opening while the valve Sis formed with an annular flange 10for abutment with the flanged ed with an annular flange 9 that surroundsDisposed within the cap is a pair of U- shaped members 11 arranged atright angles to each other and integrally joined at their centers. Thelegs of these U-shaped members 11 are formed with laterally disposedears 12 at their ends which are secured to the upper wall of the cap 6by removable fastenings 13.

An expansible coil spring 14 is supported on the U-shaped members andhas its lower end riveted to the latter, as indicated at 15. The upperend of this spring 15 is turned at right angles and embedded in theunder face of the cap as shown at 16. In order to prevent the valve 8from having any tendency to shift laterally with respect o the coilspring 14 when the former is in unseated position, a depending annularflange 17 extends from the under face of this valve 8 and overlies theupper convolutions of the spring 14.

The upper face of the valve 8 is formed with upstanding radiallydisposed ribs 18 against which the mouth of the nozzle of the fillinghose is adapted to be engaged to space the latter from the upper face ofthe valve 1 8 so that the water may pass freely from the $0 nozzle.

In operation, it will be obvious that upon pressing the nozzle ofafilling hose against the ribs 18, the valve 8 will be moved downwardly,away from its seat, -against the tension of the spring 14. Afterdisengagement of the nozzle from the ribs 18 of the valve 8 will bereturned to closed position by the coil spring 14. i

It is to be understood that the form of my invention herein shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size and arrangement of parts may beresorted to .without departing from the spirit of the invention or thescope of the subjoined claim.

Having thus described my invention, what I claim as new and desire tosecure and protect by Letters Patent of the United States, 1s:

A closure having a central opening, a valve normally seated in theopening, a pair of U-shaped members arranged at right angles to eachother, each rovided with an extension at its upper en said extensionssecured to the underface of the closure, a

coil spring having convolutions of substanheld against lateral movement,and a detially the same area as the area of the valve pending flangecarried by the under face of and engaged with the under face of the thevalve and receiving the top convolution "alve, the lower end of the coilspring being of the spring, whereby this end of the spring extendedthrough the lJ-shaped members at is held against lateral movement.

its places of intersection and formed with a head wherein the lower endof the spring is HARRY A. MAYBERRY.
